For four years, I read textbooks. Thousands of pages of summaries, which never once inspired me or left a memorable impression. I was a dutiful student, but I admit to skipping a few (hundred) pages here or there during my undergraduate degree (B.Sc. Psychology). There were several rare-yet-memorable occasions when it was required to actually read the source material, to go back and read some of the old greats. I had a wonderful professor for neuropsychology who was so passionate about Luria, that I actually tried to read some of his work. But mostly, I read textbooks. It was not until years later, during my graduate degree (M.A. Counselling Psychology), that I was exposed to the original works of Adler, Bowlby, Jung, and Rogers. The reading kindled a fire in my heart. I jumped into Frankl, Freud, May, and Piaget on my own time. I was encouraged by my clinical and thesis supervisors to identify those psychologists whose works I found most stimulating and read, read, read. Once, when I expressed dismay about hitting a wall in my thesis, one of my mentors at the university said "it sounds like you need to read more." She was right. In a six-month period, I devoured more than 1000 pages of Carl Rogers' articles and books and watched every video I could dig up of the old man in action. I can honestly say that the experience was cathartic and enlightening.
As is often the case with catharsis and insight, I also felt frustration for the way things had been before. Why hadn't I read Freud in first year psychology? Why had our professors told some deprecatory remarks about Freud's obsession with sex and a 5-bullet-point overview of his developmental theory (which was forgotten 1-month post-class)? Shouldn't we have been tasked with reading at least part of "Attachment and Loss" in the developmental psychology course? Why were Bruner and Loftus absent from cognitive psychology class? How could it be that, in a four-year period, I had read so little of the "old greats"?,
So, I have decided to use that frustration to a constructive end. I have borrowed a list from an article published by Steven Haggbloom and 10 of his colleagues called "The 100 most eminent psychologists of the 20th century," which was published in 2002. From now on, I'll call this "the eminence study." I encourage you to actually read the eminence study if you are curious about the way the research was conducted. The authors endeavored to create as objective as possible a way of measuring "eminence" but have faced critical feedback about the rank ordering of the list. If you would like to learn more about how they defined "eminence" in the study, click this link. For the purposes of this article, I'm going to use the more plainly stated "who are the most influential psychologists?" even though the terms are not exactly the same.
I have written this article for the students of psychology in the world. You do not have to be enrolled at a college or university to be a student of psychology. Anyone with a curiosity and desire to learn more about behaviour and the mind is a student of psychology. This article is a starting point for you. For each of the psychologists on the list in the eminence study, I have written one sentence to summarize why this person was so influential in psychology. These summaries are necessarily flawed. It's not really possible to reduce a person to a sentence. So, if you have any feedback about a better summary for any person on this list, please let me know and I will consider your suggestions. When you read that one-sentence summary, you might suddenly have an idea, see something in your imagination, or recall a memory from your own life. If that happens, this is the sign. It's time to follow your curiosity. Stop reading this article, and go "read the old greats" for yourself. Dive in wherever feels right for you and enjoy the ride. When you find one person you love, it often leads to the next one. Try not to fret about what you "should" read and, instead, follow what you love. It is my hope that you can use this article to find the psychologist(s) whose work speaks to you, the people who have already done the hard work to investigate the same topics that you find most compelling, and then... read.
The List
The List is in the same order as the eminence study. The List shows each person’s full name, their year of birth and death (in brackets), and a single sentence summary of this person's influence in psychology. I have provided links to suggested reading (through Google Scholar or Goodreads) and viewing (through YouTube) for each person. I have biases and I have probably made mistakes. (For transparency’s sake, I am fond of Piaget, Rogers, Maslow, Jung, Bruner, Bowlby, Luria, and Vygotsky. You may notice differences in the quality of each entry due to my liking of these people.) Finally, you may encounter terminology that you do not know as you read. I have put together a list of Psychology Terms that you can use as you read.

What is Eminence?
Webster’s Encyclopedic Dictionary defines “eminent” as “distinguished, widely thought of as superior in some way, outstanding, conspicuous” and “eminence” as “distinction in society or in a profession” as well as “a piece of high ground.” Both terms (words) come from the Latin word eminare, a verb that means “to stand out.” So, the eminence study sought to name the 100 people from 1900-1999 who were the most distinguished and superior or those who “stand out” the most.
When psychologists do research, they need to give an “operational definition” for the important terms they use. An operational definition is a more specific definition of a term that makes it possible to research. This usually means making the term measurable or testable. In the eminence study, the most important word is “eminence.” Haggbloom and colleagues operationally defined “eminence” as a combination of six different variables. Three variables are quantitative, which means that they can be measured by a number. The quantitative variables in the eminence study are the person’s number of (a) journal citations, (b) introductory psychology textbook citations, and (c) survey responses. When a researcher or writer quotes or refers to another person’s research or writing, it is called a “citation.” The survey given in variable (c) asked 1,725 members of the American Psychological Association (APA) to name the three greatest psychologists in their own specialization (or “branch” of psychology). The survey also asked these people to name as many of the greatest psychologists in the 20th century in the “overall field of psychology.”
To the Persons not on The List
Women have been treated atrociously throughout the history of science. Joan Erikson does not appear on The List, yet her husband does, despite her significant contributions to the theory of ego development across the lifespan. Eleanor Jack Gibson faced decades of gender discrimination, doing unpaid work at Cornell University for 16 years. Anna Freud's lesbianism is still a hush-hush topic, swept under the rug of history, despite the fact that her family accepted her and her tremendously valuable contributions to psychotherapy.
Many of the most important women in the history of psychology do not appear on The List. Mary Calkins was the first female president of the APA. Melanie Klein and Karen Horney transformed psychoanalysis and made therapy more accessible to "normal" people. Mamie Phipps Clark conducted some of the first studies on the effects of discrimination. Her master's thesis, in which she studied the experience black pre-school-aged children in segregated schools, was conducted in 1939, years before desegregation. Play therapy, among the only effective means of therapy for children younger than 5, became what it is today because of Virginia Axline and Dora Kalff. Brenda Milner, referred to here as "the founder of neuropsychology, published her most recent research paper at 97 years of age and was still speaking publicly at 100. Marsha Linehan's "Dialectical Behaviour Therapy" has radically improved the lives of many thousands of people. Judith Herman brought public consciousness to the uncomfortable realities of incest and trauma, which has since lead to the development of trauma-informed practices in counselling, education, massage, medicine, and psychotherapy. Carol Gilligan's early publications in moral development was dogma-shattering and she continues to be one of the most important voices in psychology today. Calkins, Klein, Horney, Clark, Axline, Kalff, Milner, Linehan, Herman, and Gilligan are all absent from the list of the most eminent psychologists of the 20th century, yet their work remains tremendously important today.
In a 2018 interview, Gilligan remarked (emphasis mine):
To the girls, women, and female-identifying persons reading this article: do not let The List discourage you. The 20th Century has past and we are in a new era for science. Let's work together to recognize the incredible women like those listed above, empower all young people with big dreams, and to take action against discrimination. Let the list of the most eminent psychologists of the 21st Century include the voices of women.
